The emerald ash borer (Agrilus planipennis), also known as EAB, is an invasive insect pest from Asia that has killed millions of trees in the United States and Canada and has caused billions of dollars of damage since it was discovered in 2002. Fortunately, its damage has been limited to ash trees—or so we thought.

Since the discovery of emerald ash borer (EAB) in 2002, the news of the infestation has been bleak. Containment efforts have failed to stop the relentless spread of this ash-killing pest and billions of trees are at risk.

Now that the dust is settling after the initial infestation in the Midwest, scientists are able to research whether any ash trees were able to survive....

Each country has its own invasive species and rampant plants with a tendency to grow out of control. In most, the techniques for dealing with them are similar - a mixture of powerful chemicals and diggers. But in the US a new weapon has joined the armoury in recent years - the goat.

Deep (and even not so deep) in the Frederick City Watershed in Frederick, Md., the Japanese stiltgrass grows in thick, luscious bunches. To the untrained eye, it's pretty, with its leafy layers blanketing the forest and transforming the ground into something out of a Grimm fairytale. But to those who know plants, the stiltgrass, along with several other invasive species , is less of a...

WORCESTER — With federal Asian longhorned beetle fighters set to take up their chain saws again to go after newly discovered infestations in the woods of Green Hill Park, at least one city councilor is calling for a resumption of pesticide treatments previously abandoned by the U.S. Department of Agriculture....

Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), working collaboratively with scientists funded by The American Chestnut Foundation, have helped confirm that addition of a wheat gene increases the blight resistance of American chestnut trees.

UXBRIDGE — In a wooded residential area off Route 122, a team of foresters and entomologists took turns looking through a scope at a small hole in the bark of a maple, maybe 55 feet up. Everyone agreed the damage came from a bird, probably a woodpecker, and not the Asian longhorned beetle.

A very good thing, since the invasive insect is not supposed to be this far beyond the infestation...
